DAILY REPORT #2005
PERIOD COVERED: 0000Z (UTC) 11/14/97 - 0000Z (UTC) 11/17/97
Daily Status Report as of 321/0000Z
1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
1.1 Completed three Sets of STIS/CCD 7802 (Daily Darks to Update
Acquisition Bad Pixel Table)
The Space Telescope Imaging Spectrograph (CCD) was used to make
calibration observations to obtain daily darks to update the acquisition
bad pixel table. These darks are intended to identify hot pixels for
update to the acquisition on-board FSW hot pixel table. Daily hot pixel
lists can also be used for science data analysis. The observations were
executed as scheduled, and no anomalies were noted.
1.2 Completed NIC/1/2/3 7447 (The Cosmological Evolution of Quasar Host
Galaxies)
The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of galaxy 4C45.51 as part of a survey to study the
cosmological evolution of galaxies which host quasars. Other point spread
function observations were taken to test the calibration of the cameras.
The observations were executed as scheduled, and no anomalies were noted.
1.3 Completed Three Sets of STIS/CCD 7782 (STIS Non-Scripted Parallel
Archive Proposal - Half Orbit)
The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one-half orbit). As mentioned in
2.1, the acquistion for the final iteration of this proposal defaulted to
fine lock on one FGS only. Otherwise, the observations were executed as
scheduled, and no further anomalies were noted.
1.4 Completed Two Sets of WF/PC-2 7619 (WF/PC-2 Cycle 7 Decontamination)
The WF/PC-2 was used to conduct a Cycle 7 Decontamination Procedure.
Ultraviolet-blocking contaminants are removed, and hot pixels cured, by
warming the CCDs to +20C for six hours. A variety of internal images are
taken before and after the decontamination in order to verify its success
and to monitor the instrument health. The procedures were conducted as
scheduled, and no problems were reported.
1.5 Completed Two Sets of STIS/CCD 7783 (STIS Parallel Science)
The Space Telescope Imaging Spectrograph (CCD) was used to make
observations taken in parallel with the prime science. The observations
were completed, and no problems were reported.
1.6 Completed Three Sets of WF/PC-2 7624 (WF/PC-2 Cycle 7 UV Flats)
The WF/PC-2 was used to make a set of ultraviolet calibration flat
images. The ultraviolet flat fields will be obtained with the
cal-channel's ultraviolet lamp using the UV filter set {F122M, F170W,
F160BW, F185W, and F336W}. The observations were executed as scheduled,
and no anomalies were noted.
1.7 Completed NIC/2 7330 (The Fueling of Active Nucleii: A NICMOS
Snapshot Survey)
The Near Infrared Camera (Camera Two) was used to probe the dark
matter distribution of NGC-4380 ,far from the center, by observing
intervening absorption from the MgII doublet (lambda 2800) in the spectrum
of one background QSO located in a geometrically optimal position. HST
observations are required because this feature is in a wavelength range not
accessible from the ground, and the QSO magnitudes and expected strength of
absorption make IUE observations unfeasible. The proposal completed as
expected with no anomalies.
1.8 Completed FGS 7485 (Dynamical Masses for the Stars in the Pre -Main-
Sequence Spectroscopic Binary 045251+3016)
The Fine Guidance Sensors were used to make astrometric observations
of the pre-main-sequence, spectroscopic, binary star STAR-04560 in order to
obtain its dynamic mass. An excellent single-lined spectroscopic orbit
already completed, which provides all of the essential orbital elements
except inclination angle and mass ratio. The observations were executed as
scheduled, and no anomalies were noted.
1.9 Completed Seven Sets of STIS/CCD 7781 (STIS Non-Scripted Parallel
Archive Proposal - Full Orbit)
The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one full orbit). The observations
were executed as scheduled, and no anomalies were noted.
1.10 Completed STIS/CCD 7352 (The Nuclear Kinematics of Kinematically
Distinct Cores)
The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of the nuclear region of the kinematically distinct core of
galaxy NGC-1700. A wave length calibration image was also taken. The
observations were completed as planned, and no anomalies were reported.
1.11 Completed Five Sets of NIC/2/3 7812 (NICMOS Modified Short One
Orbit Parallel)
The Near Infrared Camera (Cameras Two and Three) was used to obtains
"JH" imaging of sky regions when another instrument is prime. Two dither
positions are obtained for each filter. . As mentioned in 2.1, the
acquistion for the final iteration of this proposal defaulted to fine lock
on one FGS only. Otherwise, the observations were completed as scheduled,
and no further anomalies were reported.
1.12 Completed Six Sets of NIC/2/3 7811 (NICMOS Modified One Orbit Parallel)
The Near Infrared Camera (Cameras Two and Three) was used to obtains
"JH" imaging, G096 and G141 spectroscopy of sky regions when another
instrument is prime. The observations were completed as planned, and no
anomalies were reported.
1.13 Completed WF/PC-2 7623 (WF/PC-2 Cycle 7 Internal Flats)
The WF/PC-2 was used to make a set of internal Cycle 7 calibration
flats which are designed to monitor the pixel to pixel flat field response
and the visflat lamp degradation, as well as detect any possible changes
due to contamination. The calibration observations were completed as
planned, and no problems were reported.
1.14 Completed Three Sets of WF/PC-2 7625 (WF/PC-2 Cycle 7 Earth Flats)
The WF/PC-2 was used to make a series of Earth flat calibration
images. These flat fields will allow mapping of the OTA illumination
pattern and will be used in conjunction with previous internal and external
flats to generate new pipeline superflats. The observations were completed
as planned, and no anomalies were reported.
1.15 Completed Six Sets of WF/PC-2 7621 (WF/PC-2 Cycle 7 Supplemental
Darks PT1/3)
The WF/PC-2 was used to make supplemental dark calibration images.
This set of calibrations is intended to obtain three dark frames every day
to provide data for monitoring and characterizing the evolution of hot
pixels. The observations were executed as scheduled, and no anomalies were
noted.
1.16 Completed Two Sets of NIC/2 7495 (Survey of Gravitational Lenses as
Cosmological Tools)
The Near Infrared Camera (Camera Two) was used to make survey
observations of objects J03.13-OFF and LBQ1009-0 by obtaining deep,
high-resolution images in the optical and near IR in order to see if they
are gravitational lenses and could be used as a cosmological tool. The
observations were executed as scheduled, and no anomalies were noted.
1.17 Completed Seven Sets of WF/PC-2 7786 (Pure Parallel Archive Survey
- Continuation)
The WF/PC-2 was used to make observations as part of an archival
survey program in which the images were taken in parallel with the prime
science observations. These observations were obtained in the ultraviolet
in a search for interesting objects. The observations were completed as
planned, and no problems were reported.
1.18 Completed WF/PC-2 6802 (Cosmology With the Medium Deep Survey)

prime science observations as part of the Medium Deep Sky Survey. The
observations were executed as scheduled, and no problems were reported.
1.19 Completed NIC/2 7219 (Ultraluminous Infrared Galaxies)
The Near Infrared Camera (Camera Two) was used to make observations
of the ultraluminous infrared galaxy 12112+0305. The luminous IRAS
galaxies are probably powered by nuclear starbursts and/or central AGNs;
many of these systems exhibit evidence of recent galactic interaction or
merging. A dark calibration image was also taken. The observations were
completed as planned, and no problems were reported.
1.20 Completed Five Sets of WF/PC-2/NIC/1/2/3 7257 (An Unbiased Redshift
Survey of Ultra-Faint Galaxies)
The WF/PC-2 and the Near Infrared Camera (Camera's One, Two and
Three) were used to make observations of the ultra-faint galaxy AC114 -
(positions 6,7,1,2,3 and 4) as part of an unbiassed redshift survey.
Near-infrared observations of these types of objects will provide a robust
estimate of the luminosity density in the distant universe, an important
constraint on theories of galaxy formation. The observations were
completed as planned, and no problems were reported.
1.21 Completed WF/PC-2 7384 (Probing the Fine-Scale Structure and Colors
of Interstellar "Cirrus" Clouds)
The WF/PC-2 was used to make observations of the NEB-220617 in order
to probe the fine-scale structure and colors of interstellar "cirrus"
clouds. The ubiquitous nature of galactic "cirrus" clouds make them both:
{1} accessible targets for the study of the properties of interstellar dust
grains, and {2} sources of confusion in investigations of distant objects
{e.g. galaxies, clusters of galaxies} at low surface brightness levels.
The observations were completed as planned, and no problems were reported.
1.22 Completed STIS/CCD/MA2 7347 (Direct Imaging of Betelgeuse)
The Space Telescope Imaging Spectrograph (CCD and MA2) was used to
make observations of the super giant star Betelgeuse (a.k.a., BD+75D325 or
Alpha Orionis). Our UV images of Alpha Orionis obtained with the FOC in
1995 {Cycle 5} are the first direct images of the surface of a star other
than the Sun. The observations were completed as planned, and no anomalies
were reported.
1.23 Completed Two Sets of WF/PC-2 7387 (T-Tauri Star Snapshot Survey)
The WF/PC-2 was used to make observations of the stars FM-Tau and
VV-Car as part of a T-Tauri class star survey. The observations were
executed as scheduled, and no anomalies were noted.
1.24 Completed NIC/2 7212 (Polarization in Galactic Nuclei)
The Near Infrared Camera (Camera Two) was used to make
polarizational observations of the galaxy NGC-1068. Comparison of these
images with corresponding visible data taken with HST will provide unique
constraints on the structure and emission mechanisms in the galaxy.
Comparison with the optical polarimetry will help to understand the
relative importance of mechanisms which produce the polarization. A dark
calibration image was also taken. The observations were completed as
scheduled, and no anomalies were reported.
1.25 Completed NIC/2 7420 (A Near-Infrared Search for Very Low Mass
Companions to Stars Within 10 Parsecs of the Sun)
The Near Infrared Camera (Camera Two) was used to make searching
observations for very low mass companions to variable star BD-05D5715.
This star is known to be within 10 parsecs of the Sun. The observations
were executed as scheduled, and no anomalies were noted.
1.26 Completed NIC/1 7804 (The Superluminal Source GRS 1915+105: A
Runaway Black Hole ?)
The Near Infrared Camera (Camera One) was used to make observations
of the superluminal binary source GRS1915+10 which has a possible run-away
black hole. It is proposed to confirm the proper motion of the binary
using NICMOS images taken one year apart. The observations were executed
as scheduled, and no problems were noted.
1.27 Completed STIS/CCD 7711 (STIS CCD G750L Fringing Flats.)
The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of GRS1915+10 in order to investigate and monitor the STIS CCD
flat-field fringing in the G750L grating at it's nominal wavelength setting
{7751A}. WAVECALs were also taken at the same gain and wavelength setting.
Typical S/N = 100 for each integration, and gain = 4 on each. The
observations were executed as scheduled, and no anomalies were noted.
1.28 Completed WF/PC-2 7289 (Spatially-Resolved FUV Spectra of the
Primary Shock in the Cygnus Loop)
The WF/PC-2 was used to make far-ultraviolet spectra of the Cygnus
Loop to determine the ionization structure behind the non-radiative,
primary shock front on the northeastern edge of the Cygnus Loop supernova
remnant. The observations were completed as planned, and no problems were
reported.
1.29 WF/PC-2 6549 (Calibration of Nearby Type Ia Supernovae as Standard
Candles: NGC 3627 and SN 1989B)
The WF/PC-2 was used to make observations of the Type Ia supernova
SN 1989B which is located in galaxy NGC-3627. The experiment is designed
to determine the mean absolute magnitude of the B and V of SNe Ia, and how
large the dispersion is about this mean. The observations were completed
as planned, and no problems were reported.
1.30 Completed WF/PC-2 7377 (Dwarf Elliptical Galaxy Snapshot Survey II)
The WF/PC-2 was used to make observations of the dwarf elliptical
galaxy FCC140 as part of Snapshot Survey II. This survey will provide
important information on the globular cluster systems of such galaxies and
the properties of their cores and nuclei. As described in 2.1, the
acquisition for this proposal failed, and observations proceeded under gyro
control with the take data flag down.
1.31 Completed NIC/2 7331 (Near-IR Properties of the Bulges of Spiral
Galaxies)
The Near Infrared Camera (Camera Two) was used to make infrared
observations of the bulge in spiral galaxy NGC-7162. Near-IR data at HST
resolution are essential for correcting for the effect of dust and will
enable us to derive robust nuclear properties for the sample. The
observations were executed as scheduled, and no anomalies were noted.
1.32 Completed STIS/CCD 7404 (STIS Spectroscopy of Markarian 78)
The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of the galaxy Markarian 78 in order to study
spectrographically the interaction between its jets and the interstellar
medium in the central few kpc of this Seyfert class galaxy. A wavelength
calibration image was also taken. The observations were completed as
planned, and no anomalies were reported.
1.33 Completed NIC/2 7228 (Imaging and Polarimetry of YSO'S)
The Near Infrared Camera (Camera Two) was used to investigate the
young stellar object (YSO) L1551-IRS5 with coronagraphic imaging,
polarimetry, and line imaging. The observations were completed as planned,
and no problems were reported.
1.34 Completed WF/PC-2 6619 (High Resolution Images of QSO Lyman Alpha
Absorbing Galaxies)
The WF/PC-2 was used to make several images of galaxy field
(Field-0906) in order to obtain high resolution observations of the Lyman
Alpha absorbing galaxies within this field-of-view. The purpose is to
directly identify the objects responsible for low and intermediate redshift
QSO Lyman-Alpha systems. As mentioned in 2.1, the acquistion for this
proposal defaulted to fine lock on one FGS only. Otherwise, the
observations were executed as scheduled, and no further anomalies were
noted.
